be evenly adjusted. It will be seen that when this is done it requires the time of the person applying the brakes and the pressure is likely to be more or less uncertain. My invention is intended to produce a simple locking member or device which can be applied to the foot lever or brake lever when the brakes are set and which will hold the brakes in said set position. My invention is intended to produce a very simple device of this kind which can be readily applied to the usual brake lever, and my invention is also intended to produce a simple form of locking device which can be adjusted readily'as to length to enable it to fit different makes of cars.

ing member of hinged parts so that it will act like a toggle and by placing it between the lever and abutment in a slightly bent posi-" tion, then straightening itout by pressure on the joint, the member will stay straight and securely lock the brake lever in'its set j "1011 end '19 for the memberll to guard position. This will be better understood from the following description. V i Reference is to be had to the accompanying in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a side elevation of my improved device showing its application to abrake lever and with the locking member in unstra-ightened position. Figure 2 is a similar view, but with the locking member straightened out.

Figure 3 is an enlarged detail, showing how In adjusting The usual application of the device is to set the brakes then place the locking member which is in the form of a locking arm bedrawings forming a part of this specification,

the locking deviceengages the foot or brake lever.

:Figure 4 is aview similar to Figure 3 but with the parts in a difierent position. Figure 5 is a brokenplan view or a modi-ified and preferred form of thedevice which renders it adjustable.

Figure 6 is a broken side elevation of the structure shown in Figure 5.

Figure 7 is a detailed perspective viewof the lever engaging tongue of the device. I

Figure 8 is a broken perspective view of-the v body portion of the locking member.

. In its simplest form, the locking member is composed of two hinged parts 10 and 11 united at the abutting endsiby a hinge: 12f

The part 11 can be bifurcated and'widened at its front end as shown at 13 so as to partly straddle and engage the foot lever 16 which is the conventional lever for setting brakes" an dthe member 11 has also preferably thereon and on the upper side a fixed shoe 14: which is adapted to engage the foot plate or pedal 15 of the lever 16 In operation, the locking member can be placed between the lever 16;. and the base of the car seat as shown in Figure 1, and the lever 16 may be pushed forward and downward in the customary way, after which the locking member is straightened out as in Figure 2 and will hold the lever 16 in its forward and downward position which is assumed when the brakes are. set.

To make thedevice applicable to all makes of cars, I prefer to have .it adjustable asto length, and in this case the form shown in Figures 5to 8 is useful. I show also a cushagainst marring the part of the, car with which it comes in contact'and the member ll: is bifurcated towards its free as n, at recelve a dju abl eate sionortongue 22. To facilitate adjustment the side walls Of the bifurcation 20 are shown provided with teeth 21 to receive 33115225 on thefsidefs of the tongue 22 and byplajcing thesepins in desired notches or teeth .21 V eb' e'ue y he gth if th we as a Whole gca eree' a ltW l e-evident h ether means can bee-used for nakingthe 'de...

vice extensible or for locking the tongue in place without affecting the invention.

The tongue or extension 22 has 1ts outer end preferably in the shape of a fork 23 to engage the lever 16, and it alsohas a shoe 24 thereon acting like the shoe 14 already referred to, to engage the pedal 15 The action of the modified form of the structure is previsely as indicated, except for the adjustable feature. The tongue 22 is adjusted as described, and when the brake lever is pushed forward the locking member is placed between the seat and the lever 16, and the locking member straightened out as described, thus securely locking the lever and holding the brakes set. 1

The foregoing illustrates simple and pre- 'termined position and means engagingthe foot pedal to position the device.

6. A brake locking device for motor cars comprising a member arranged to extend between the brake lever of the car and an abutment,-said member having a bifurcated end,

keys in said end, and a tongue adjustably held in the said keys'andhavingits free end shaped to engage the aforesaid brake lever, and means secured to said tongue to engaging the foot pedal to retain said member in position.

In testimony whereof, I have signed my name to this specification this 5th day of October, 1925.

ferred forms of the device, butfrom the dea scription given it will be seenthatmany other forms of a removable locking device, extendment on the car can be designedwithout departing from the principle of this invention, which While simple in form, saves the time of a person holding the brake set and-also holds the brakes steadily and more securely than would an individual.
